The wisdom of the crowd is the process of taking into account the collective opinion of a group of individuals rather than a single expert to answer a question. A large group’s aggregated answers to questions involving quantity estimation, general world knowledge, and spatial reasoning has generally been found to be as good as, and often better than, the answer given by any of the individuals within the group.
An intuitive and often-cited explanation for this phenomenon is that there is idiosyncratic noise associated with each individual judgment, and taking the average over a large number of responses will go some way toward canceling the effect of this noise. This process, while not new to the information age, has been pushed into the mainstream spotlight by social information sites such as Wikipedia and Yahoo! Answers, and other web resources that rely on human opinion. In the realm of justice, trial by jury can be understood as wisdom of the crowd, especially when compared to the alternative, trial by a judge, the single expert.

Extraordinary Popular Delusions and the Madness of Crowds is a history of popular folly by Scottish journalist Charles Mackay, first published in 1841. The book chronicles its subjects in three parts: National Delusions, Peculiar Follies, and Philosophical Delusions.
Despite its journalistic and rather sensational style, the book has gathered a body of academic support as a work of considerable importance in the history of social psychology and psychopathology. The subjects of Mackay’s debunking include economic bubbles, alchemy, crusades, witch-hunts, prophecies, fortune-telling, haunted houses, popular follies of great cities, and popular admiration of great thieves.

The Wisdom of Crowds is a 2004 book written by American journalist James Surowiecki about the aggregation of information in groups, resulting in decisions that, he argues, are often better than could have been made by any single member of the group. The book presents numerous case studies and anecdotes to illustrate its argument, and touches on several fields, primarily economics and psychology.
The opening anecdote relates Francis Galton’s surprise that the crowd at a county fair accurately guessed the weight of an ox when their individual guesses were averaged (the average was closer to the ox’s true butchered weight than the estimates of most crowd members, and also closer than any of the separate estimates made by cattle experts). The book relates to diverse collections of independently-deciding individuals, rather than crowd psychology as traditionally understood, however its title is an allusion to Charles Mackay’s ‘Extraordinary Popular Delusions and the Madness of Crowds,’ published in 1841 (which chronicled economic bubbles, witch-hunts, crusades, and similar phenomena).

The Monroe Institute (TMI) is a nonprofit education and research organization devoted to the exploration of human consciousness, based in Virginia. TMI, which claims a policy of no dogma or bias with respect to belief system, religion, political or social stance, was founded by Robert Monroe after he experienced an ‘out of body experience,’ now also commonly referred to as OBEs. Activities includes teaching various techniques, based on audio-guidance processes, in order to expand consciousness and explore areas of consciousness not normally available in the waking state.
Controlled studies of the Institute’s technology suggest that it is effective as an analgesic supplement and can reduce hospital discharge times. The Institute has an affiliated professional membership, and also publishes scientific papers on a subset of its own studies of altered states of consciousness. In its in-house laboratory, these states or focus levels are typically induced by delivering Hemi-Sync signals to subjects performing relaxation procedures inside a shielded, sense-depriving isolation tank. Progression through states is detected and monitored by measurement of peripheral skin temperature, galvanic skin response and DC skin potential voltage.

‘One-Dimensional Man: Studies in the Ideology of Advanced Industrial Society’ is a 1964 book by philosopher Herbert Marcuse. The work offers a wide-ranging critique of both contemporary capitalism and the society in the Soviet Union, documenting the parallel rise of new forms of social repression in both these societies, as well as the decline of revolutionary potential in the West.
Marcuse argues that ‘advanced industrial society’ created false needs, which integrated individuals into the existing system of production and consumption via mass media, advertising, industrial management, and contemporary modes of thought.

The Clock of the Long Now is a proposed mechanical clock designed to keep time for 10,000 years. The project to build it is part of the Long Now Foundation, a private organization that seeks to become the seed of a very long-term cultural institution. The project was conceived by American inventor Danny Hillis in 1986: ‘I want to build a clock that ticks once a year. The century hand advances once every one hundred years, and the cuckoo comes out on the millennium.I want the cuckoo to come out every millennium for the next 10,000 years.’
The first prototype of the clock began working on December 31, 1999, just in time to display the transition to the year 2000. At midnight on New Year’s Eve, the date indicator changed from 01999 to 02000, and the chime struck twice. That prototype, approximately two meters tall, is currently on display at the Science Museum in London. The first full-scale clock’s manufacture and site construction is being funded by Jeff Bezos, who has donated $42 million, and is located on his Texas land.

Heroin chic was a look popularized in mid-1990s fashion and characterized by pale skin, dark circles underneath the eyes, and angular bone structure. This waifish, drug-addicted look was the basis of the 1993 advertising campaign of Calvin Klein featuring Kate Moss photographed by Vincent Gallo.
Emaciated features and androgyny were a reaction to ‘healthy’ and vibrant look of models such as Cindy Crawford, Claudia Schiffer, and Heidi Klum. A 1996 article in ‘The Los Angeles Times’ charged that the fashion industry had ‘a nihilistic vision of beauty’ that was reflective of drug addiction.

Radical chic is a term coined by journalist Tom Wolfe in his 1970 essay ‘Radical Chic: That Party at Lenny’s,’ to describe the adoption and promotion of radical political causes by celebrities, socialites, and high society. The concept has been described as ‘an exercise in double-tracking one’s public image: on the one hand, defining oneself through committed allegiance to a radical cause, but on the other, vitally, demonstrating this allegiance because it is the fashionable, au courant way to be seen in moneyed, name-conscious Society.’
Unlike dedicated activists, revolutionaries, or dissenters, those who engage in radical chic remain frivolous political agitators. They are ideologically invested in their cause of choice only so far as it advances their social standing. ‘Terrorist chic’ is a modern expression with similar connotations. This derivative, however, de-emphasizes the class satire of Wolfe’s original term, instead accentuating concerns over the semiotics of radicalism (such as the aestheticization of violence).

A monofin is a type of swimfin typically used in finswimming and free-diving. It consists of a single surface attached to footpockets for both of the free-diver’s feet. Monofins were introduced in 1972, by a Ukrainian finswimming club, and have been used for finswimming competitions since, allowing monofin swimmers to reach speeds of 12km/h. Monofins can be made of glass fiber or carbon fiber. The diver’s muscle power, swimming style, and the type of aquatic activity the monofin is used for determines the choice of size, stiffness, and materials.
To differentiate between the use of monofins and conventional fins, the latter are sometimes referred to as stereo fins or bi-fins. The monofin swimmer extends arms forward, locking hands together, locking the head between the biceps. The undulating movement starts in the shoulders, with maximum amplitude towards the hips, the legs almost don’t bend to transfer the movement to the monofin. This technique is called the dolphin kick.

The hedonic treadmill is the supposed tendency of humans to quickly return to a relatively stable level of happiness despite major positive or negative events or life changes. According to this theory, as a person makes more money, expectations and desires rise in tandem, which results in no permanent gain in happiness. Brickman and Campbell coined the term in their essay ‘Hedonic Relativism and Planning the Good Society’ (1971). During the late ’90s, the concept was modified by Michael Eysenck, a British psychology researcher, to become the current ‘hedonic treadmill theory’ which compares the pursuit of happiness to a person on a treadmill, who has to keep working just to stay in the same place. The general idea of the ‘Hedonic (or Happiness) Set Point’ has gained interest throughout the field of positive psychology.
Research supports a three-factor model, where our level of happiness is 50% determined by genetics, 10% determined by outside circumstances, and 40% determined by intentional activities. That last factor, of intentional activities, is the focus of positive psychology, especially because not all activities are equally effective at helping one to reach the higher end of their happiness range. One study concluded that life goals along with personality characteristics are important determinants of one’s subjective well-being. Life goals that enrich one’s relationships and social resources, such as altruistic and family oriented goals, increase their level of subjective well-being. On the other hand, materialistic life goals, such as monetary achievement, have a negative effect on people’s overall subjective well-being.

Moneybomb is a neologism coined in 2007 to describe a grassroots fundraising effort over a brief fixed time period, usually to support a candidate for election by dramatically increasing, concentrating, and publicizing fundraising activity during a specific hour or day. The term was first applied to a supporter-led fundraiser on behalf of presidential candidate Ron Paul.
The effort combines traditional and Internet-based fundraising appeals focusing especially on viral advertising through online vehicles such as YouTube, Facebook, and online forums. In the case of lesser-known candidates it is also intended to generate significant free mass media coverage the candidate would otherwise not receive. The term has also been used as a verb and apparently arose from analogy with the neologism ‘googlebomb,’ a method of search engine optimization.

Flash fiction is a style of fictional literature or fiction of extreme brevity.
There is no widely accepted definition of the length of the category. Some self-described markets for flash fiction impose caps as low as three hundred words, while others consider stories as long as a thousand words to be flash fiction. In one particular format, established by Steve Moss, Editor of the New Times, the requirement is 55 words; no more and no fewer. Another, unspecified but frequently held, requirement is that the title may be no more than seven words.
